Terrible Vodacom

I called into the cancellation department to cancel my existing contract. I was then offered the Samsung galaxy S20FE for the premium of R339 and to stay on my current package. I accepted the offer and asked the consultant to courier the phone. He then tells me his confused and his co worker sitting next to him will call me back immediately, her name was Jennel, she did call me back however when I explained to her the story she said no they cannot give me that contract. I said the calls are recorded and please listen to what was offered , then she tells me the phone is not available and hang up on me. This was so rude.
